8 Claims.

This invention relates to lamp mountings and particularly to panel mountings for lights such as signal lights, pilot lights and illuminating'devices, generally, and it consists in the constructions,

' arrangements and combinations herein described and claimed.

It is a special object of the'invention to provide a. construction which will enable the production of the device at an extremely low cost, and

which will embody features of structure making for the ready mounting, replacement of lamps and efiiciency in other respects.

It is also an object to provide the body of the mounting with novel means for attachment to a mounting ring.

It is a still further object of the invention to enable the body of the article to be formed from fiat stock material by a simple blanking and bending operation.

Additional objects, advantages and features of invention will be apparent from the following description, considered in conjunction with the accompanying drawing, wherein:

Figure 1 is a side elevation of the mounting, partly in section.

Figure 2 is a side elevation of the body of the assembly and associated mounting ring.

Figure 3 is a-top plan view thereof, part of the body being broken away. I

Figure 4 is a perspective view of the ring.

Figure 5 is a; similar view of the body.

Figure 6 is a sectional view through the ring, one leg of the body being broken away.

In carrying out the invention, I provide a sub.- stantial U-shaped body member ill having a pair of parallel leg members H, the outer ends of a which are slotted longitudinally as at 2, defining a tongue l3, which as shown, is positioned medially of the legs. The tongues 83 extend beyond the shoulder portions M of the legs and respective tongues are bent laterally in opposite directions defining lips i5.

Medially of the bight E6 of the body member in, there is provided an aperture H for mounting a socket 8. The socket 68 may be mounted in any convenient manner, and in any event, will include contact arms i9 establishing electrical circuit with the socket.

The body member it is detachably mounted upon a ring 20, the ring having a pair of oppositely positioned slots 2| cut in the inner peripheral edges of the ring with which communicating transverse slots 22 are formed, the latter slots extending from the inner to the outer. periphery of the ring. The depth of the slots 2| are slightly greater than the thickness of the metal defining the tongues I3, so that when the tongues are positioned in the slots they will lie spaced inwardly of screw threads 23 formed upon the interior of the ring 20. The lips I5 lie within the slots 22 flush with the upper face of the ring.

The inherent resilience of the legs I! tend to spring the legs outwardly in opposite directions,

thus securely binding the member in to the ring 20, and by reason of the fact that the end portions I4 snugly abut the adjacent face of the ring, the body I 0 will be firmly held to the ring.

A ferrule 24 is employed, screw threaded interiorly and exteriorly as at 25 and 26, the exterior threads 26 being complemental to the threads 23 of the ring, and the interior threads 25 receive the threaded shank 21 of a jewel mounting 28. The mounting 28 in the present instance is shown substantially as a cylinder, the outer end seating a jewel or lens 29. Preferably the ferrule '24 has a bezel 30 cooperable with a panel for mounting the assembly, as will be described hereinafter.

In use, with the body to secured to the ring 20, and it is desired to mount the assembly, a panel 3! is employed suitably apertured to receive the ferrule 24 therethrough. The threads 26 being engaged with the threads 23 of the ring 20, the ferrule is screwed home so as to draw the ring 20 snugly against the panel. If found necessary, a plurality of washers 32 may be interposed between the panel 3! and the ring 26, this depending upon the thickness of the panel and the desired positioning of the socket it. After securement of the ring and ferrule, the jewel mounting 28 is engaged with the threads 25 of the ferrule. When it is desired to remove or replace a bulb in the socket it, this may be done from the rear of the panel or access to the bulb may be had by removing the jewel mounting 28, as desired.

While I have specifically shown and described a preferred construction, this is by way of illustration only, and I consider as my own, all such modifications in structure as fairly fall within the scope of the appended claims.

I claim:

1. A lamp mounting consisting of a U-shaped body member defining a bight portion and having a pair of parallel spaced resilient legs, an interiorly threaded ring member, the ring member having a pair of longitudinal slots therein for reception of the free ends of the leg members, a ferrule threadedly engaged with the threads of the ring, the ferrule having a shoulder complemental to the ring for clamping action upon a tit panel interposed therebetween, and a lamp socket mounted in the bight portion of the body member aligned with the ferrule.

2. A lamp mounting consisting of a U-shaped body member having a pair of parallel, spaced resilient legs, the free ends of the legs being lon gitudinally slotted to define a tongue, shoulder portions upon opposite sides of the tongues, each of the tongues having an oppositely disposed lateral lip member, an interiorly threaded ring member, the ring member having a pair of longitudinal slots therein for reception of respective tongues, laterally extended slots in the outer face of the ring in communication with the longitudinal slots for reception of respective lip members, the tongues and lips lying within their respective slots when said shoulders are in abutting engagement with the adjacent face of the ring member, a ferrule member threadedly engaged with the threads of the ring member; the ferrule having a shoulder complemental to the ring for clamping action upon a panel interposed therebetween, and a lamp socket carried in the bight portion of the U-shaped body member, aligned with the ferrule.

3. A lamp mounting comprising a generally U-shaped body having parallel spaced leg portions, each leg having a laterally extending flange at its free end, a clamping collar having a clamping surface adapted to be clamped against a supporting wall or the like, complementary clamping means associable with a margin of said collar and actuable to urge said collar against said wall, said collar having axially extending recesses along said margin adapted to receive the end portions of said legs and radially extending recesses formed in the said clamping surface and adapted to receive said lateral flanges when the legs are arranged in said first named recesses for 40 holding said body member against said wall.

4. A lamp mounting as defined in claim 3 wherein the said end portions of said legs comprise tongues located adjacent the free extremities of said legs and bent laterally at a point in- 45 termedlate of said tongues, and wherein said recesses are complementarily formed to receive said tongues.
